AI could be the buzzword of the decade and there’s almost no corner of modern technology it won’t touch. 

In the banking and financial services sector, where customer trust and regulatory compliance are paramount, AI is being used to identify risks and make decisions faster. But it’s also causing some complications. AI and machine learning are also becoming increasingly integrated into web application security strategies to help monitor, detect, and respond to threats with greater speed and precision. Let’s take a deeper look at the evolving relationship between AI and web application security in the banking and financial services industry. 

How AI is shaping application security in the banking and financial services industry

AI-driven capabilities have huge potential to make security operations more efficient and scalable. Automated testing tools are evolving, along with the capabilities and security protocols of AI agents. 

AI use cases in AppSec

From intelligent triage to exploit validation, AI is becoming a force multiplier in application security.

Here’s how it’s making an impact:

Vulnerability prioritization

AI models help teams cut through the noise by scoring vulnerabilities based on exploitability, asset criticality, and business context.

Automated AppSec triage and remediation

AI can classify findings, group related issues, and suggest likely fixes, streamlining developer workflows and reducing response time.

Vulnerability context

AI enhances vulnerability context by correlating findings with known CVEs, exploit activity, and threat actor patterns.

Challenges of AI-powered AppSec

While AI introduces major efficiencies to application security, it also introduces risks, especially when misunderstood or over-relied upon. Here are some of the key challenges covering many different facets of AI in AppSec.

False positives and alert fatigue

AI models could overflag issues, overwhelming teams with noise. Without validation, these findings erode trust and consume valuable cycles.

Lack of context awareness

AI can miss business logic and user intent. It may surface vulnerabilities without understanding impact—leaving teams unsure whether to act or how.

Insecure code generation

As developers increasingly use AI tools to write code, there’s a growing risk of introducing insecure logic, requiring more robust testing earlier in the pipeline.

Expanded attack surface

AI models, APIs, and dependencies create new avenues for attack, especially in applications that integrate ML or offer AI-driven features.

Data poisoning and model manipulation

For orgs building their own models, poisoned training data or adversarial inputs can compromise behavior or trustworthiness.

Supply chain exposure

Relying on third-party AI models or datasets introduces dependency risks, particularly if these components lack transparency or security review.

AI use cases in banking and financial services

In the banking and financial services industry, AI is being used to scale workforce efficiency, help customers, comply with regulations, personalize experiences, and even make decisions. Use cases include:

• Fraud detection: Analyzing real-time transaction patterns to block fraudulent activity.
• Credit scoring and loan processing: Evaluating creditworthiness using nontraditional data and machine learning models.
• Algorithmic trading: Using AI to identify and act on market trends at machine speed.
• Risk management: Monitoring credit, market, and operational risks using predictive models.
• Customer service: Powering chatbots and virtual assistants to reduce support costs and improve service.
• Personalized services: Tailoring products and recommendations to individual customer profiles.
• Document processing: Automating extraction and validation of data from financial records using natural language processing (NLP) and intelligent document processing (IDP).
• Compliance: Reviewing data and logs to ensure adherence to financial regulations.

Challenges of AI in banking and finance

Artificial intelligence brings common challenges that all industries will face. Banking and finance is no exception and raises some unique questions of its own. 

Data privacy

Financial institutions must be able to protect sensitive data used by AI models and ensure transparency and customer consent.

Algorithmic bias 

AI models could perpetuate biases present in training data or surface ethically questionable insights, potentially leading to unfair or discriminatory outcomes.

Transparency 

Understanding how AI algorithms reach their decisions is crucial for accountability and regulatory compliance.

Compliance 

The evolving regulatory landscape for AI in finance requires financial institutions to adapt their AI strategies and ensure compliance. Technological changes can outpace regulations, creating security gaps. 

How AI secures financial platforms in real time

While AI introduces important questions around ethics and compliance, it’s also becoming essential to real-time defense. Financial institutions increasingly rely on AI to monitor, detect, and respond to threats as they happen—especially in customer-facing platforms and APIs.

AI is increasingly used to detect and respond to threats in real time across banking systems, from blocking fraudulent login attempts to identifying suspicious API activity. Financial institutions rely on AI to monitor privileged access, detect credential stuffing, and mitigate automated attacks as they unfold. 

Real-time threat data and AI

To improve threat detection, financial organizations can feed AI models large volumes of attack data. While this improves pattern recognition and prediction over time, it also introduces risk, particularly when integrated via tools like Model Context Protocol (MCP). Initially lacking native authorization, MCP creates gaps that could make it possible for AI agents to overreach into sensitive systems.

The evolution of secure AI

To address these security concerns, an OAuth 2.1-based authorization protocol has been added to MCP, giving financial institutions more control over what AI systems can access. However, many legacy banking systems weren’t built with these protocols in mind, making widespread adoption slow and complex—especially for institutions with older infrastructure.

Agentic AI adds more complications. These systems don’t just analyze data, they take action (initiating transfers, managing transactions), introducing a new layer of risk. If compromised, these agents could cause real-world damage. Banks must now consider how to monitor AI-driven system actions, not just data access or model outputs.

The emerging field of AI security testing

Financial institutions developing their own AI tools, like fraud engines, chatbots, or recommendation models—need ways to test those systems against threats like prompt injection and jailbreaks. AI security testing tools help simulate attacks, but vary widely in quality and scope. Without standard benchmarks, it’s hard to compare tools or gauge whether they’re sufficient for finance-specific threat models.

While AI security testing focuses on protecting the models themselves, securing the applications that surround and deliver those models remains equally critical, especially in complex financial environments. Let’s take a closer look at how AI can be leveraged in application security. 

AI + DAST: a powerful combination

It’s no secret that Invicti takes a DAST-first approach to application security, prioritizing the speed and detection of runtime vulnerabilities above all else. But modern DAST is no longer just about finding vulnerabilities, it’s about proving which ones matter and giving teams the context they need to fix them more quickly. Invicti combines AI-powered scan guidance with proof-based validation to give security leaders in banking and finance what they actually need: real risk insights backed by hard evidence. 

The value of Invicti’s AI-powered, proof-based approach

Our AI isn’t bolted on because it’s a buzzword. It’s thoughtfully designed and incorporated safely into the areas of AppSec where it’s most valuable: 

• Smarter scan targeting: AI helps inform where to scan based on dynamic application behavior and previous vulnerability trends.
• Predictive risk scoring: AI analyzes historical exploit data and application context to anticipate which vulnerabilities are most likely to be exploited—enabling teams to prioritize what matters before it becomes a breach.
• Proof-based validation: Only confirmed, exploitable issues are flagged—cutting false positives and freeing up security teams to focus on real threats.
• Confidence at every step: Each issue comes with proof of exploitability, so development and security teams can take immediate action without second-guessing.

This balance of AI-supported efficiency and proof-backed accuracy helps teams scale security efforts with confidence. AI innovations added to the Invicti platform have boosted its already industry-leading scanning capabilities, identifying 40% more critical vulnerabilities while maintaining a 99.98% confirmation accuracy, along with a 70% approval rate on AI-generated code remediations through our integration with Mend. Security and development teams are finally able to have a high-level of trust in their coverage while innovating at speeds they previously thought unrealistic.
